Figure 1 Conceptual framework for ‘Get (absorption)-Save
(resorption)-Return (decomposition)’ continuum and its linkage with leaf
economics spectrum. (a) , the ‘GSR’ continuum comprises an
active trade-off between root nutrient absorption and leaf nutrient
resorption as well as a passive trade-off between leaf nutrient
resorption and leaf-litter decomposition; (b) , the
acquisitive-strategy species running on a fast lane get more nutrients,
resorb less nutrients, and return nutrients fast; (c) , the
conservative-strategy species running on a slow lane get less nutrients,
resorb more nutrients, and return nutrient slowly. In b and c, circle
size indicates relative effect strength and grey line indicates no
relationship between root absorption and leaf-litter decomposition.
Figure 2 Pairwise correlations among nutrient-associated
processes across all species (a, n = 15) and species hosting
arbuscular mycorrhizal (b, AM, n = 8) and ectomycorrhizal (c,
ECM, n = 7) fungi. The size of the circle is proportional to the
correlation coefficient. The cross indicates that the correlations are
not significant, P > 0.05. NAP is nitrogen
acquisitive potential, PAP is phosphorus acquisitive potential, NRE is
nitrogen resorption efficiency, NRP is nitrogen resorption proficiency
(the negative of nitrogen concentration in leaf litter was used here),
PRE is phosphorus resorption efficiency, PRP is phosphorus resorption
proficiency (the negative of phosphorus concentration in leaf litter was
used here), and ML is mass loss.
Figure 3 Principal component analysis (PCA) for green leaf
traits, including specific leaf area (SLA), leaf tissue density (LTD),
green leaf carbon concentration (GCC), green leaf nitrogen concentration
(GNC), green leaf phosphorus concentration (GPC), and green leaf lignin
concentration (GLC) for all species. (a), trait loading biplot; (b)
species distribution in the one-dimensional trait space. AM, arbuscular
mycorrhizas; ECM, ectomycorrhizas.

Figure 4 Relationships of the PC1 axis score with phosphorus
acquisitive potential (a, PAP), leaf-litter phosphorus concentration (b,
LPC) and mass loss (c, ML) for all species (n = 15, blank
circles) and species hosting arbuscular mycorrhizal (AM, n = 8,
red upper triangles) and ectomycorrhizal (ECM, n = 7, purple
lower triangles) fungi.
